Description of Anti-foaming: An anti-foaming agent prevents the formation of foam and defoamers eliminate existing foam. These terms are often used interchangeably and at IngreCore we use anti-foaming for both terms. An Anti-foaming agent is a component commonly added in chemical processes that work with liquids. Anti-foaming ingredients or chemicals will reduce or prevent the generation of foam. This is important, as foams pose a significant problem in industrial processes. Foams can lead to problems in the final appearance of the product, as well as problems in the production or packaging process, for example when air from the foam enters pumps.
Anti-foaming agents come in a wide variety with an even wider range of specifications. In general an anti-foaming agent does not dissolve in the medium and has some surfactant abilities. Commonly used anti-foaming agents include insoluble oils, silicone solutions such as IngreSil DM350 and IngreSil DM100, glycols, waxes and even some alcohols.
